On Evans's Vague Object from Set Theoretic Viewpoint

Gareth Evans proved that if two objects are indeterminately equal then they are different in reality. He insisted that this contradicts the assumption that there can be vague objects. However we show the consistency between Evans's proof and the existence of vague objects within classical logic. We formalize Evans's proof in a set theory without the axiom of extensionality, and we define a set to be vague if it violates extensionality with respect to some other set. There exist models of set theory where the axiom of extensionality does not hold, so this shows that there can be vague objects.     

Subcellular interactions between parallel fibre and climbing fibre signals in purkinje cells predict sensitivity of classical conditioning to interstimulus interval

Classical conditioning of the nictitating membrane response requires a specific temporal interval between conditioned stimulus and unconditioned stimulus, and produces an incrase in Protein Kinase C (PKC) activation in Purkinje cells. To evaluate whether biochemical interactions within the Purkinje cell may explain the temporal sensitivity, a model of PKC activation byCa ²⁺, diacylglycerol (DAG), and arachidonic acid (AA) is developed.Ca ²⁺ elevation is due to CF stimulation and IP3 inducedCa ²⁺ release (IICR). DAG andIP ₃ result from PF stimulation, while AA results from phospholipase A2 (PLA ₂). Simulations predict increased PKC activation when PF stimulation precedes CF stimulation by 0.1 to 3 s. The sensitivity of IICR to the temporal relation between PF and CF stimulation, together with the buffering system of Purkinje cells, significantly contribute to the temporal sensitivity.     

Harmony and Autonomy in Classical Logic

Michael Dummett and Dag Prawitz have argued that a constructivist theory of meaning depends on explicating the meaning of logical constants in terms of the theory of valid inference, imposing a constraint of harmony on acceptable connectives. They argue further that classical logic, in particular, classical negation, breaks these constraints, so that classical negation, if a cogent notion at all, has a meaning going beyond what can be exhibited in its inferential use.I argue that Dummett gives a mistaken elaboration of the notion of harmony, an idea stemming from a remark of Gerhard Gentzen"s. The introduction-rules are autonomous if they are taken fully to specify the meaning of the logical constants, and the rules are harmonious if the elimination-rule draws its conclusion from just the grounds stated in the introduction-rule. The key to harmony in classical logic then lies in strengthening the theory of the conditional so that the positive logic contains the full classical theory of the conditional. This is achieved by allowing parametric formulae in the natural deduction proofs, a form of multiple-conclusion logic.     

Different corticostriatal patterns of L-DOPA utilization in patients with untreated schizophrenia and patients treated with classical antipsychotics or clozapine

Positron emission tomography (PET) has been shown to be of great importance in elucidating the mechanism of action of antipsychotic drugs. In psychotic patients L-[11C]DOPA PET has been used to demonstrate some differences in dopaminergic activity compared with that in healthy volunteers. Ten healthy volunteers were investigated with PET and L-[11C]DOPA. Ten drug-free patients with psychosis, nine stable schizophrenics treated with clozapine, and nine stable patients treated with classical antipsychotics were also investigated with L-[11C]DOPA. Principal-component analysis was employed for the analysis of L-[11C]DOPA Ki values across a number of corticostriatal brain regions. These data revealed a significant three-component model with clear-cut separation between healthy controls and patients with unmedicated schizophrenia. Stable optimal treatment with either classical neuroleptics or clozapine partially, albeit differentially, reversed the aberrant patterns seen in drug-free schizophrenia. It can thus be concluded that schizophrenia is associated with abnormal patterns of L-[11C]DOPA utilization in corticostriatal systems. Treatment with clozapine or classical neuroleptics induces partial, albeit differential, normalization of the abnormal patterns seen in untreated schizophrenia.     

A review of climate and culture research in selling and sales management

Despite the extensive literature on organizational climate and culture and their impact on an organization's sales activities, the diversity of theoretical perspectives makes it difficult for sales professionals and scholars to understand the effect of specific climate- and culture-related factors on the performance of salespeople and sales units in an organization. The objective of this article is to clarify the conceptual underpinnings of organizational climate and culture research within the sales context through an extensive review of extant literature. In doing so, we offer a critical review of research on organizational climate and culture, a conceptual frame for viewing the literature across different levels of analysis, and specific questions to guide future research. We also make a case for more research on industry-level climate and culture in the sales context.     

Understanding the factors that determine workplace coaching effectiveness: a systematic literature review

Meta-analytic results have established that workplace coaching is effective, however, little is known about the determinants of coaching effectiveness. This paper reports an inclusive systematic literature review, covering the quantitative and qualitative research on workplace coaching. We focus on seven promising areas in the current workplace coaching literature that emerged by the synthesis of 117 empirical studies: self-efficacy, coaching motivation, goal orientation, trust, interpersonal attraction, feedback intervention, and supervisory support. The major contribution of our paper is the systematic integration of well-established theoretical constructs in the workplace coaching context and the new insights we provide in the synthesis of these literatures. Based on our review, we provide specific recommendations to be addressed in future research, including recommended research methodologies, which we propose will significantly progress the field of workplace coaching theory and practice.     

Childhood sexual abuse trauma-causing dynamics experienced by women survivors: A scoping literature review

This scoping literature review reports on the major themes to emerge from 23 retrospective studies on the trauma-causing dynamics experienced by women survivors of a historical childhood sexual abuse (CSA) trauma. We identified the studies from searching the following data bases for the period 1983–2016: EbscoHost (Academic Search Premiere, Africa-Wide Information, E-Journals, ERIC, PsycARTICLES, PsycINFO, SocINDEX), SAePublications, Science Direct, CrossRef (APA PsycNET), Google scholar (ResearchGate), PubMed Central, and Cochrane Reviews. For the selection criteria, we included empirical studies on self-reported trauma-causing dynamics experienced by women survivors, without restriction on method of study. Results from the thematic analysis of findings suggest the women survivors appear to be living with historical traumatic sexualisation, betrayal of trust, social stigmatisation, powerlessness, developmental arrest, and revictimisation. Historical traumas should be considered in counselling support interventions with women self-reporting CSA.     

Does a single session of reading literary fiction prime enhanced mentalising performance? Four replication experiments of Kidd and Castano (2013)

Prior experiments indicated that reading literary fiction improves mentalising performance relative to reading popular fiction, non-fiction, or not reading. However, the experiments had relatively small sample sizes and hence low statistical power. To address this limitation, the present authors conducted four high-powered replication experiments (combined N?=?1006) testing the causal impact of reading literary fiction on mentalising. Relative to the original research, the present experiments used the same literary texts in the reading manipulation; the same mentalising task; and the same kind of participant samples. Moreover, one experiment was pre-registered as a direct replication. In none of the experiments did reading literary fiction have any effect on mentalising relative to control conditions. The results replicate earlier findings that familiarity with fiction is positively correlated with mentalising. Taken together, the present findings call into question whether a single session of reading fiction leads to immediate improvements in mentalising.     

Nothingness and the aspiration to universality in the poetic ‘making’ of sense: an essay in comparative east–west poetics

As a contribution to comparative East-West poetics, this essay descries a common resource of Western and classical Chinese literatures in certain “apophatic” modes of thought and discourse that are oriented to what cannot be said, to what is manifest only in and through a certain evasion and defiance of all efforts to verbalize and conceptualize it. This argument is developed in critical counterpoint with the work of interpreting Chinese classical poetry and thought by the French philosopher and sinologist François Jullien. Jullien acutely apprehends and elegantly expounds the deeply apophatic bent of Chinese poetics. However, he sets Chinese thought and poetry categorically apart from Western approaches, whereas my analysis brings them together under the aegis of their common inspiration from the experience of the limits of language vis-à-vis an unspeakable origin of thinking and its source in reality.     

The Catcher in the Rye and the ill member of the group: Holden Caulfield and adolescent development

This paper is an attempt to explore J. D. Salinger’s The Catcher in the Rye (1951/1958) in relation to Winnicott’s theories of adolescent development, also with regard to psychodynamic theories of symbolism, mourning, defence mechanisms and containment. I consider the significance of the novel’s protagonist and narrator Holden Caulfield. What is the reason for the enduring popularity of his voice and its influence on the tone of subsequent adolescent literature? To answer this question, I examine the role this iconic, troubled character may play in the development of the adolescent reader.
